Installation & Application Notes

Never strike bearings directly — use a bearing press or driver set. Heat housing (not bearing) to ease installation. Replace bearings in sets where applicable. Check housing bore diameter before fitting — out-of-round bores destroy new bearings.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Early signs of bearing failure include audible humming or grinding noises during operation and increased vibration from the affected component. If ignored, the wear will accelerate, leading to significant play and potential misalignment of the supported shaft. Continued operation risks damage to the shaft and housing, potentially causing extended downtime.

Installation Tip

Ensure that the bearing bore and the shaft are perfectly clean and free from any debris or burrs before installation. Avoid hammering the bearing directly; use a proper press or driver to apply force evenly to the bearing's outer or inner race.

Service Note

Inspect the shaft and housing for any signs of wear or scoring when replacing this bearing.
